BOW
The bow is the forward part of the hull of a ship or boat, the point that is most forward when the vessel is underway. Both of the adjectives fore and forward mean towards the bow. The other end of the boat is the stern.
The bow is designed to reduce the resistance of the hull cutting through water and should be tall enough to prevent water from easily washing over the top of it. On slower ships like tankers, a fuller bow shape is used to maximise the volume of the ship for a given length.
A "wet bow" results from seawater washing over the top of the hull. A raked stem can help to reduce the wetness of the bow. Aside from making the deck slippery, water can corrode the metal of the ship. If the temperature is low enough this water can also freeze on the deck, rails, turrets, and other exposed surfaces, increasing the topside weight.
Several types of bows exist. These include:
Tumblehome
Raised foredeck
Reverse sheer
Conventional clipper
Low-cain spoon bow
High-cain spoon bow
X-Bow (Developed by the Ulstein Group)
Ram bow
Bulbous bow

STEM
The stem is the very most forward part of a boat or ship's bow and is an extension of the keel itself. The stem is the curved edge stretching from the keel below, up to the gunwale of the boat. The stem is more often found on wooden boats or ships, but not exclusively. The stem is part of the physical structure of a wooden boat or ship that gives it strength at the critical section of the structure, bringing together the port and starboard side planks of the hull.
There are two styles of stems: plumb and raked. When the stem comes up from the water, if it is perpendicular to the waterline it is "plumb." If it is inclined at an angle to the waterline it is "raked." (E.g., "The hull is single decked and characterized by a plumb stem, full bows, straight keel, moderate deadrise, and an easy turn of bilge.")
Because the stem is very sturdy, the top end of it may have something attached, either ornamental or

    The Mary Rose was substantially rebuilt in 1536. This rebuilding turned the ship of 500 tons into one of 700 tons, and added an entire extra tier of broadside guns to the old carrack-style structure. It was built according to the carrack-style with high “castles” in the bow and stern with a low waist of open decking in the middle. The shape of the hull has a so-called tumblehome form and reflected the use of ship as a platform for heavy guns. Above the waterline, the hull gradually narrows to compensate for the weight of the guns and to make boarding more difficult. The molded breadth, the widest point of the ship roughly above the waterline, was about 12 metres (39 ft) and the keel about 32 metres (150ft).…

A small raised portion of the wave cut platform may be left marking the former position of the stack. Then this is known as stump1.…

    Long ships were sea vessels made and used by the Vikings from the Nordic countries for trade, commerce, exploration, warfare, and etc. The long ship appeared in its complete form between the 9th and 13th centuries. The character and appearance of these ships have been reflected in Scandinavian boat-building traditions until today. The particular skills and methods employed in making long ships are still used worldwide, often with modern adaptations. These unique ships are characterized as a graceful, long, narrow, light, wooden boat with a shallow-draft hull designed for speed. The ship's shallow draft allowed navigation in waters only one meter deep and permitted beach landings, while its light weight enabled it to be carried over portages. Long ships were the epitome of Scandinavian naval power at the time, and were highly valued…

    Longships were naval vessels made by the Vikings that originated from Scandinavia and Iceland. The design of the longships was intentionally different from other boats, so the speed would be better. Longships were made of wood and were lighter. The design of longships changed over many years. Although, the brainstorming of the architecture structure of this ship began in the Stone Age. The creation of the longship was complete between the 9th and 13th centuries. Another name for longships was dragonships. The average speed for ships built by Vikings was five to…

    “The blind thing in his doubled fury broke/ a hilltop in his hands and heaved it after us./ Ahead of our black prow it struck and sank/ whelmed in a spuming geyser, a giant wave/ that washed the ship stern foremost back to shore./ I got the longest boathook out and stood/ fending us off, with furious nods to all to put their backs into a racing stroke-/ row, row, or perish. So the long oars bent/ kicking the foam sternward, making head/ until we drew away, and twice as far.”(9. 524-534)…

    Trees hung sideways at an angle and the green water morphed into a muddy brown color. I kept only a wet towel covering my body from the cold burning rain. Without warning, the whaling winds gathered themselves to lift the immaculate, heavy, beaten pontoon above the flowing water. Fortunately, the air filled top of the pontoon snapped like a stick within second of being air borne. This was a short moment of relief for my family but it still was not finished.…

    The longbow was a great contributor to the English success in the battle of Agincourt. This enabled the archers to " rain approximately 10 arrows per minute per man down upon the enemy" (Henry V). The English army had "6000 soldiers and out of that 5000 soldiers were longbow men" (http://www.longbow-archers.com). This allowed for greater impact before and during hand to hand combat. The longbow was such an important part of the…
